Kit Crankshaft HQ Racing Connecting rod CNC and C4 Bearings Minarelli Horizontal VOCA Racing

Kit Voca Racing HQ Racing consisting of crankshaft and bearings, intended for compatible Minarelli horizontal engines. It is a suitable option for repair, replacement, or lower engine assembly work in setups that require a reinforced crankshaft and bearings suitable for high mechanical demands.

The Voca Racing HQ Racing crankshaft maintains the original stroke and is designed for performance builds on Minarelli horizontal engines. It incorporates a CNC-machined connecting rod, 12 mm pin, and a silver needle bearing 12x15x15, offering a configuration intended for high-end tuning and sporting use.

Its counterweighted design with aluminum inserts helps reduce the weight of the assembly and improve engine response. In addition, the closed crankshaft design helps increase pre-compression in the crankcase, a common feature in high-performance setups.

The kit is completed with Voca Racing VCR-RD72166/C4 bearings, a specification intended for applications where greater internal clearance is required to cope with temperature, rotational speed, and high workloads. By including the crankshaft and bearings in the same set, it facilitates a more complete and consistent installation when opening the engine.

Important

Before purchase or installation, it is necessary to verify the exact compatibility with the vehicle and the engine configuration. Installing a crankshaft requires suitable tools, checking tolerances, correct bearing installation, and inspection of the assembly before closing the engine.

It is essential to carry out balance checks before installation. Manufacturers may deny the warranty if a balancing fault is detected after the crankshaft has been installed in the engine.
